Start with one ship and a small purse. Build a trading empire that spans the seas. Argosy is a deep economy and trading sim set in the harbor cities of a late-medieval merchant league, where prices move with real supply and demand, and the biggest fortunes go to the merchant who reads the market best.

Rise from unknown shopkeeper to lord mayor: buy low, sell high, build a fleet, and climb the ranks of merchant society until you govern the cities you once traded in. Play solo against rival AI merchants, or take the same living economy online.

A Living Economy

No price is fixed. Every city produces some goods and runs short on others, and the market reacts to every deal you make.

• Trade 20 goods across cities linked by real supply and demand.

• Spot a shortage before your rivals and turn one city's famine into your fortune.

• Build factories to refine raw timber, hemp and iron into goods worth far more.

A Fleet That Runs Itself

Grow from one vessel into a fleet, then put it to work without steering every voyage.

• Crew historical sailing ships, from nimble coastal traders to heavy ocean haulers.

• Assign captains who grow more skilled the longer they sail.

• Draw automated trade routes on an interactive map, then pause or resume them at will.

• Set up warehouses and production in the cities that matter most.

Rise Through the Ranks

Wealth opens doors, but rank demands deeds: ships owned, contracts fulfilled, feasts hosted, pirates defeated.

• Climb from shopkeeper to councillor and lord mayor.

• Stand for election, set tax rates, and shape the cities you trade in.

• Keep citizens supplied, then turn that goodwill into political weight against rivals.

• Win the League-wide Grand Factor election for the ultimate triumph.

Naval Combat and Piracy

Not every sail on the horizon comes in peace. Escort your convoys, or fly the black flag yourself.

• Fight tactical battles, landing broadsides while keeping your hull out of the line of fire.

• Board and plunder enemy ships to seize their cargo, or take the hull entire.

• Hoist the Jolly Roger and prey on the trade lanes, if you can survive the hunt that follows.

Scheme, Pray, and Stand Trial

A merchant's life has its dark side. Hire tavern contacts to steal, forge, and sabotage, and answer for it when the courts catch wind.

• A full legal system: file lawsuits, hire advocates, bribe jurors, or settle out of court.

• Trials play out in phases before a sworn jury, with a verdict that carries real weight.

• Attend church to stay in the clergy's good graces and keep heresy charges at bay.

Sail Beyond Your World

The Expedition Atlas sends ships to other worlds entirely. Dispatch a captain on a solo voyage, or cross live into another player's running economy as a real market participant. Discoveries are shared across your guild.

Outwit Rival Merchants

You share the world with AI merchants who trade, build and scheme by the same rules you do. The routes they run shape the very economy you are trying to master, and when trade goes quiet, the world stirs with raiders, contracts, and unexpected callers.

Build and Share Your Own Maps

A full map editor lets the world you trade in be one you made yourself.

• Generate coastlines and rivers, or import an image to trace a real map.

• Place your own cities and decide what each port produces, needs and trades.

• Export and share your maps, and play any custom world solo or online.

Play Solo or Online

Build your empire alone against the AI, or take it online and compete head to head in one shared, living economy. Invite friends through Steam and pick up multiplayer sessions from a full server save.
